The invention provides a bridge anti-collision active early warning system and method, and the method comprises the steps: collecting a monitoring image of a ship channel, and segmenting the monitoring image into a plurality of ship suspicious graph blocks; determining a plurality of edge candidate points according to the gradient vector of each pixel point in the ship suspicious image block, and determining the gradient direction value of each edge candidate point; extracting homonymous pixel groups with consistent gradient directions based on the gradient direction values, and performing feature analysis on the ship suspicious blocks according to the homonymous pixel groups to obtain shape feature indexes; marking a target ship based on the shape feature index of each ship suspicious graph block, and analyzing the yaw risk degree in the driving state according to the navigation images of the target ship at different navigation moments; and performing early warning based on the yaw risk degree. According to the scheme, the driving state of the target ship driving to the bridge is pre-warned based on the yaw risk degree, and accurate analysis of the ship position and the navigation direction can be realized under visual interference, so that the safety of ship navigation is improved.
本申请提供了一种桥梁防撞主动预警系统及方法,采集船舶航道的监测图像,将监测图像分割为多个船舶可疑图块;依据船舶可疑图块中每个像素点的梯度向量确定多个边缘候选点,确定各个边缘候选点的梯度方向值;基于各个梯度方向值提取梯度方向一致的同向像素组,依据同向像素组对船舶可疑图块进行特征分析,得到形状特征指数;基于每个船舶可疑图块的形状特征指数标记出目标船舶,根据目标船舶在不同航行时刻下的航行图像分析行驶状态下的偏航风险度;基于偏航风险度进行预警。上述方案基于偏航风险度对目标船舶驶向桥梁时的行驶状态进行预警,可在视觉干扰下实现对船舶位置和航行方向的准确分析,以提升船舶航行的安全性。
